For similar physical–chemical processes in chemistry and biology, the phenomenon of linear enthalpy– entropy compensation (EEC) is a thermodynamic puzzle remaining unexplained for a long time. The basic thermodynamic rules do not rigorously support the EEC phenomenon. In some restricted conditions EEC may appear linear with nonrealistic (i.e. hypothetical) values of the slope (the compensation temperature), and the intercept (the compensation free energy). The compensation temperature (Tcomp) is normally higher than the experimental temperature. Compensation temperature may even become negative, and the related phenomenon is called anti-enthalpy–entropy compensation (AEEC). Negative Tcomp is unrealistic. Both EEC and AEEC are not explainable; the derived Tcomp and ΔGcomp (free energy of compensation) of the EEC plot are impractical. The neglect of the Gibbs free energy changes (of similar processes in the EEC plot) makes the phenomenon arbitrary. In a restricted condition (i.e. narrow free energy window range) linear compensation is an assumed solution. In overall consideration, the reported correlations are physicochemically uncertain. The said compensation may arise for both kinetic and equilibrium processes. The manifestations are nearly same. Our demonstration and discussion in this paper pertain to equilibrium processes.Keywords

The first scientific paper on microemulsion was published in 1943 by Schulman and Hoar of Cambridge University. Microemulsion is basically made up of oil, water, surfactant and a short-chain alcohol, acid or amide (called ‘cosurfactant’). They were called swollen micelles or by some other names but not microemulsion in 1943 or after. It was rechristened ‘microemulsion’ in 1959 by Schulman et al. who were then at New York’s Columbia University. Research in microemulsion became popular in 1980s when there loomed a large spectre of oil scarcity and its eventual effect on human civilization as we are aware today. Microemulsion was thought to be important for tertiary oil recovery. It has also been found to be useful for nanoparticle synthesis, in pesticide formulation, in drug delivery, and in many other ways, and the research on it still has a great potential and importance. In the 75 year of its innovation (and documentation in the literature), a short but succinct article with its flavour and importance is presented here.Keywords
